f-attrin
- Attribute byte. All normal files, plus those with the attributes
specified by setting this parameter, are to be included. To specify attributes,
set the bits as follows:

|
Success/file found

| 2
|
Error
|
-
f-handle
- The find handle. This field is set by the find-first function
(see f-action above) and should not be altered until the corresponding
terminate search has been done.
-
f-attrout

-
f-size
- The size of the file in bytes.
-
f-fileout
- The name of the file found, space-terminated.
Comments:
To find a single file, use the find-one function.
To find several files, use the find-first function and then use the find-next function repeatedly. When there are no more matching files, find-next returns with 1 in f-error. If you do not keep calling find-next until this happens, you must finish by calling the terminate-search function.
The f-handle field should be set to zero before you execute the find-first or find-one function. After that, if you are using the first/next/terminate sequence this field should not be changed until after the terminate search. If you are using the find-one function this field is automatically reset to 0 after that call.
If at any time f-error returns 1 or 2, a terminate search has been carried out automatically, and you should not execute the terminate-search function.
This routine cannot be used to check the existence of a network share resource, such as \\server1\share1, but it can be used to locate files or directories on that share, such as \\server1\share1\*.
